O presente trabalho decorreu na empresa Fertiprado, Sementes e Nutrientes,
Lda., na Herdade dos Esquerdos, Vaiamonte, mais concretamente no departamento de
Investigação e Desenvolvimento. O seu objetivo global é avaliar o efeito de inoculantes,
com base em consórcios microbianos, em diferentes espécies forrageiras (Trifolium
suaveolens Willd, Lolium multiflorum Lam., Avena strigosa Schreb. e x Triticosecale Witt.).
As sementes destas espécies foram inoculadas com grupos específicos de
microrganismos e foram avaliadas em campo e em vaso, para estudar o efeito na
produção de biomassa aérea e radicular das culturas. Para as leguminosas foram testados
os inoculantes: 1(consórcio de Rhizobium leguminosarum), 2 (Rhizoglomus irregulare,
Funneliformis mosseae e Trichoderma koningii) e 3 (consórcio de Rhizobium leguminosarum).
Para as gramíneas, foi avaliado o efeito do Inoculante 2 (Rhizoglomus irregulare,
Funneliformis mosseae e Trichoderma koningii), o Inoculante 4 (Xanthomonas sp.,
Pseudomonas sp. e Stenotrophomonas rhizophila) e o Inoculante 5 (Pseudomonas sp. e
Paenibacillus sp.). Nas leguminosas, os melhores resultados em termos de biomassa e
rebrote, foram observados em plantas inoculadas com o Inoculante 3. Nas gramíneas, o
Inoculante 4 aparenta ser o mais eficiente, quando consideramos a produção de
biomassa aérea e radicular. Este estudo corrobora as evidências bibliográficas de que a
pré-inoculação de leguminosas e gramíneas pode influenciar positivamente a
produtividade destas culturas. Os resultados obtidos evidenciam a importância da
seleção criteriosa de consórcios microbianos para a otimização da produção forrageira,
podendo reduzir a utilização de adubos de síntese química, a redução de custos ao
agricultor e, assim, promover práticas mais sustentáveis na agricultura.
The present work took place in the company Fertiprado, Sementes e Nutrientes, Lda., in Herdade dos Esquerdos, Vaiamonte, more specifically in the department of Research and Development. Its overall objective is to evaluate the effect of inoculants based on microbial consortia on different forage species (Trifolium suaveolens Willd, Lolium multiflorum Lam., Avena strigosa Schreb. e x Triticosecale Witt.). The seeds of these species were inoculated with specific groups of microorganisms and were evaluated in the field and in pots to study the effect on the production of aerial and root biomass of crops. For legumes, the inoculants were tested: 1 (Rhizobium leguminosarum consortium), 2 (Rhizoglomus irregulare, Funneliformis mosseae, and Trichoderma koningii), and 3 (Rhizobium leguminosarum consortium). For grasses, the effect of Inoculant 2 (Rhizoglomus irregulare, Funneliformis mosseae, and Trichoderma koningii), Inoculant 4 (Xanthomonas sp., Pseudomonas sp., and Stenotrophomonas rhizophila), and Inocolant 5 was evaluated. (Pseudomonas sp. e Paenibacillus sp.). In legumes, the best results in terms of biomass and regrowth were observed in plants inoculated with Innoculant 3. In grasses, Inoculant 4 appears to be the most efficient when we consider the production of aerial and root biomass. This study corroborates bibliographic evidence that pre-inoculation of legumes and grasses can positively influence the productivity of these crops. The results obtained highlight the importance of careful selection of microbial consortia for the optimization of forage production, which can reduce the use of chemically synthesized fertilizers, reduce costs for the farmer, and thus promote more sustainable practices in agriculture.
